And finally: Smash the London Marathon in 2016 with wearable tech

Welcome to our weekly round-up of rumours, rumblings and half-facts. And Finally is the home of everything that isn't quite an announcement or launch in wearables. All those juicy tidbits that sound amazing because, you know, they might not be real.

Read on for a definitive round up of the less credible stories of the week.

Real Google Maps coming to Android Wear

We're pretty excited about some of the new features coming to Android Wear including Wi-Fi support, gestures and always-on apps. But it seems lots of people missed a clue in Google's gif as to what's next. It showed what looks like a full smartwatch version of Google Maps as opposed to the limited navigation on there at the moment.

We could also expect to see pop up notifications in a future update. The feature wasn't detailed at all in the blog post but we imagine it means alerts that run over other apps.

Apple Watch has a tiny battery

Big new Apple device, big old iFixit teardown. The team who have taken apart and inspected your favourite smartphones are at it again to find out all the specs and components Apple forgot to mention.

That includes the fact that the Apple Watch runs on a 205mAh battery, around half of the LG G Watch R's battery. Now we know that the Watch needs nightly charging and the G Watch R can reach a day and a half or two days but it's not as straightforward as that. As with the iPhones, Apple will have optimised its hardware and software to eke out as many hours as possible out of the Watch's battery.

Apple Watch Edition returns inspected

As teased before the launch, new details have emerged about the process of returning an 18-karat gold Apple Watch Edition. 9to5Mac has published a document sent to Apple Store staff on the stringent guidelines, after all these are watches that can cost up to $17,000.

Floor staff will inspect the smartwatch visually to check for cracks and damage. Then a Genius bar employee will inspect it with a microscope and gold weighing scales to ensure no gold has been removed. The standard 14 day Apple return timeframe still applies.
